Application filed September 19, 1916, Serial No. 120,997. Renewed August10, 191?.

To all whom it may concern:

Be it known that I, GROVER 0. LONG, a citizen of the United States,residing at Lakeland, in the county of Polk, State of Florida,haveinvented certain new and use ful Improvements in Hydrocarbon-Burners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains, to make and use the same.

This invention relates to oil burners, and has particular reference toburners in which oil and steam are mixed to provide a burning fuel.

The object of the invention is to improve the construction ofhydrocarbon or oil burners. In this connection,it is intended to soconstruct the burners that when they do require adjustment, theadjustments can be made by the simple operation of a single adjustingelement. Furthermore, the device according to my construction is madeentirely accessible for cleaning by the removal of a single head plate.

A further object of the invention is to construct a burner of thischaracter in which the arrangement of parts insures a low oilconsumption without waste from imperfect atomization. To this end, Ihave provided a burner in which the oil is vaporized, or brought to astate closely approximating vaporization, this vaporization beingbrought about by the use of the steam which eventually becomes mixedwith the vaporized oil to form the fuel.

With the above objects in view and such other objects as may hereinafterappear, my invention will now be fully set forth and described,reference being had to the accompanying drawings.

In the drawings Figure 1 is a longitudinal section taken through theburner structure, certain pipe connections being shown in elevation,

Fig. 2 is a. section on line 22 of Fig. 1,

Fig. 3 is a section on line 3-3 of Fig. 1, and

Fig. 4 is a-longitudinal section of a modified form of the nozzle.

Referring more particularly to the drawings, 1 represents a cylindricalbarrel which terminates at its front end in a conical head 2, and atubular mouth piece 3. The rear end of the barrel 1 is closed by a headplate Specification of Letters Patent.

4:, which is secured to the barrel 1 preferably, by means of cap screws5 which pass through a flange 6 formed on the rear end of the barrel.The central portion of the head plate 1 is formed into a boss 7 which iscentrally apertured to receive a heating coil 8, the latter beingsurrounded where it passes through the boss 7 with a packing 9 held inplace by a bushing 10. The stem 11 of the coil is threaded substantiallythroughout its length to receive the adjusting wheel. 12, the latterhaving an annular flange 13 upon its inner face which bears upon theface of the boss 7. Thus when it is necessary to clean the burner,removal of the face plate 4 gives complete access to the interior of thebarrel 1, and when it becomes necessary to adjust the burner within thebarrel, the coil can be readily positioned by means of the hand wheel12. The coil 8 may be constructed with any suitable material such asbrass or iron and is provided with a suitable number of coils, andterminates in the axially projected stem 14 which may ridelongitudinally through the spider 15 secured between the walls of thebarrel 1. The head or nozzle 16 which is mounted upon the forward end ofthe stem 14 is a frusto-conical shell having its rear face 17 centrallyapertured and bossecl so as to be threaded upon the stem 14:, and havingits forward end positioned so as to partially close the inner end of thetubular mouth 3 with its transverse web or face 18. The periphery of thenozzle 16, near the largest circumference thereof is provided with anannular series of openings 19 through which the oil or vaporized oilescapes at right angles to the direction of the stem 14. Thread ed intothe tubular mouth 3 is the nozzle pipe 20 of the burner, which may be ofany suitable length to meet the requirements of the particular furnacein which the burner is being used, but which is seldom less thantwenty-four inches in length. The forward end of the nozzle pipe isfitted with a nozzle 21 of any required type.

' The pipe 22 is the oil supply pipe and is connected to the rear end ofthe stem 11 by means of a union 23, which is of such character as topermit the adjustment of the coil. A valve 2 1 controls the supply ofoil to the coil 8. A. steam pipe 25 enters the barrel 1 through the wallof the latter near the rear end of the burner, and a bypass 26 from thepipe 25 to the oil pipe 22 provides for the removal of sediment from thecoil 8 and the nozzle 16.

From the foregoing, it will be evident that I have constructed anextremely simple and practical burner which embodies the principles ofvaporizing and atomizing fuel. The construction is such that a very highdegree of temperature is attainable, and by reason of the preliminaryvaporizing of the fuel, no'particles of oil emerge from the burner toincrust the boiler sheet or tubes and there is practically no soot orcarbon.

In the form shown in Fig. 4, the coil is dispensed with, this form ofburner be ing sometimes employed where superheated steam is accessible.Instead of the coil 8, a

continuous stem 8 is carried in the boss 7 and the spider l5, and theaction of the super-heated steam upon the oil in the stem 8 vaporizes italmost completely before it passes out of the nozzle 16, and the actionof the. steam on the remaining liquid causes its atomization before itreaches the nozzle 21.

What I claim as my invention is 1. A hydrocarbon burner, comprising incombination, a cylindrical barrel terminating in a conical head, an oilcoil mounted in said barrel, a nozzle on the forward end of said coil, anozzle on said barrel and a steam inlet for the barrel, said nozzle onthe coil forming with said conical head a restricted passage, and havingopenings for ejecting vaporized oil against said conical head across thepath of the steam passing to the nozzle of the barrel. 7

2. A hydrocarbon burner, comprising in combination, a cylindrical barrelterminating in a conical head, an oil coil mounted in said barrel, anozzle on the forward end of said coil, said nozzle being positioned infitted and slightly spaced relation within the conical barrel head,means for permitting ture, in the presence of two witnesses.
